37fb27fa1c Python: change type of LibraryCallable::getACall 
The other callables return control flow nodes,
so it is slightly inconsistent for this to return a
data flow node, but it does make models based
on API graphs nicer.

This is not necessary as long as `LibraryCall` only
includes unresolved calls.

e3280c8a3e Python: handle TODO 
although this is not actually tested,
so we may have to adjust once we use it.
But the _very_ generic implementation is modeled on the Ruby code.

0f95992b2f Python: remove NonLibraryDataFlowCallable

fa2da2f3ec Python: remove NonLibraryNormalCall 
it is not necessary to distinguish these calls,
so we remove the class from the hierarchy.

895f5480c2 Python: Added recursion guard 
to ensure that the call graph seen by type tracking
does not include summary calls resolved by type tracking.

(I tried inserting a similar test into the Ruby codebase,
 and it still compiled)

To get this to compile, I had to move the resolution of summary calls
out of the data flow nodes and into the `viableCallable` predicate.
This means that we now have a potential summary call for each
cfg call node. (I tried using the base class, `DataFlowCall`, for this
but calls to `map` got identified as class calls and would no longer
be associated with a summary.)

It is possible that the "NonLIbrary"-layers the were inserted into the
hierarchy can be removed again.

1649ec7cd7 Python: Describe current naming scheme 
In the hope that this will enable a better one.
It looks like
- type tracking should currently be mutually recursive with data flow
  (this needs investigation)
- type tracking already supports special methods
  (we should probably have a test for this)
